Emergence of stable meron quartets in twisted magnets
Kyoung-Min Kim, Gyungchoon Go, Moon Jip Park +1
The investigation of twist engineering in easy-axis magnetic systems has revealed the remarkable potential for generating topological spin textures, such as magnetic skyrmions. Her…
Controllable magnetic domains in twisted trilayer magnets
Kyoung-Min Kim, Moon Jip Park
The use of moiré patterns to manipulate two-dimensional materials has facilitated new possibilities for controlling material properties. The moiré patterns in the two-dimensional m…
Exceptional Classifications of Non-Hermitian Systems
Jung-Wan Ryu, Jae-Ho Han, Chang-Hwan Yi +2
Eigenstate coalescence in non-Hermitian systems is widely observed in diverse scientific domains encompassing optics and open quantum systems. Recent investigations have revealed t…
Topological Phase Transitions of Generalized Brillouin Zone
Sonu Verma, Moon Jip Park
It has been known that the bulk-boundary correspondence (BBC) of the non-Hermitian skin effect is characterized by the topology of the complex eigenvalue spectra, while the topolog…
Realization of Non-Hermitian Hopf Bundle Matter
Yung Kim, Hee Chul Park, Minwook Kyung +6
Line excitations in topological phases are a subject of particular interest because their mutual linking structures encode robust topological information of matter. It has been rec…
